heating curve?
Answers
My prediction is that as you put substances is that is will delay the boiling point of the water as it is heated

A given mass of gas in a rigid container is heated from 100 °C to 300 °C. Which of the following best describes what will happen to the pressure of the gas? The pressure will
Answers
Pressure will increase by a factor of 3.
Explanation:
PV = nRT —> Ideal gas equation.
Taking into account the Gay-Lussac's Law, the pressure will increase by a factor less than three.
Gay-Lussac's law indicates that, as long as the volume of the container containing the gas is constant, as the temperature increases, the gas molecules move faster. Then the number of collisions against the walls increases, that is, the pressure increases. That is, the pressure of the gas is directly proportional to its temperature.
In summary, when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, the pressure of the gas decreases.
Mathematically, Gay-Lussac's law indicates that the ratio of pressure to temperature is constant:
[tex]\frac{P}{T} =k[/tex]
Studying two different states, an initial state 1 and a final state 2, it is satisfied:
[tex]\frac{P1}{T1} =\frac{P2}{T2}[/tex]
In this case, a given mass of gas in a rigid container is heated from 100 ° C to 300 ° C, that is, it is heated from 373 ° K to 573 ° K. This indicates that the temperature is increasing by a factor less than three. Since pressure is directly proportional to temperature, pressure must increase in the same proportion.
Finally, the pressure will increase by a factor less than three.

"Can you get tan from a campfire?".
Answers
Answer: You could if you had a special fire letting out UV light, but if not, you'd probably get burned first.
Explanation:
Fire does emit UV, which causes tanning, but it also emits a lot of other wavelengths, including infrared which is primarily responsible for heating. If you build a really big fire, one that would emit enough UV to tan, it would also emit a huge amount of infrared which will burn you sooner than you getting a tan.
No, you cannot get a tan from a campfire. A tan is a result of exposure to ultraviolet (UV) radiation, specifically UVB rays, which are primarily emitted by the sun. UVB rays penetrate the skin and stimulate the production of melanin, a pigment that darkens the skin as a protective response.
A campfire does not emit significant amounts of UV radiation. The light emitted by a campfire is primarily in the visible spectrum, which does not have the same wavelength as UVB rays. Therefore, sitting near a campfire will not provide the necessary UV radiation to induce tanning.
Campfires can emit infrared radiation, which can generate heat and potentially cause burns or damage to the skin if one is too close for an extended period.

Answer:
765 g Co(NH₃)₆Cl₃
General Formulas and Concepts:
Reading the Periodic Table of ElementsExplanation:
Step 1: Define
2.86 mol Co(NH₃)₆Cl₃
Step 2: Define conversions
Molar Mass of Co - 58.93 g/mol
Molar Mass of N - 14.01 g/mol
Molar Mass of H - 1.01 g/mol
Molar Mass of Cl - 35.45 g/mol
Molar Mass of Co(NH₃)₆Cl₃ - 58.93 + 6(14.01) + 18(1.01) + 3(35.45) = 267.52 g/mol
Step 3: Dimensional Analysis
[tex]2.86 \ mol \ Co(NH_3)_6Cl_3(\frac{267.52 \ g \ Co(NH_3)_6Cl_3}{1 \ mol \ Co(NH_3)_6Cl_3} )[/tex] = 765.107 g Co(NH₃)₆Cl₃

Answer:
D. All of the above
Explanation:
Molecules, ions, and pure elements might be included in a chemical reaction. Therefore, option (d) is correct.
What is a chemical reaction?A chemical reaction can be described as a reaction that brings the chemical conversion of one chemical substance to another chemical substance. The reactions cause chemical changes that include the rearrangement of electrons in order to create and break bonds between atoms.
The compound or molecules which are primarily utilized in a reaction are called reactants. Chemical reactions give products, which possess characteristics different from the reactants of the reaction.
Chemical reactions take place at a definite rate of reaction at a given concentration, temperature, and pressure. The rate of reaction increases with the rising temperature of the reaction as more activation energy is available for reactant molcules collisions.
Therefore, in a chemical reaction reactants and products can be present as Molecules, ions, and pure elements.

Fossils of sea creatures have been found near the top of Mount Everest (8848m above the sea level). How do you think they could have got there?
Answers
Answer:
Continental Drift
Explanation:
The fossils of sea creatures could have reached the top of Mount Everest due to the continental drift theory suggested by geophysicist, Alfred Wegener. To exaggerate, a piece of evidence that supports Wegener’s hypothesis towards a continental drift is the fact that fossils of sea creatures can’t just end up in any random place like Mount Everest. He suggests that there must be something behind this and gradually it led to his well-known theory. His hypothesis towards a continental drift suggests that his second observation was that fossils of the same prehistoric species were found in different continents that were way apart. There was just no way that all the organisms could cross the oceans and reach all of these places.

Which system is used to measure physical properties?
The International System of Units (SI), is commonly known as the metric system. This system is used as the international standard for measurement. Most scientists use the International System of Units which is also known as the metric system in order to measure physical properties of elements. The metric system is a system of measurement that uses meter as base units of length (distance), liter for volume, and , and gram for weight or mass. We use units that are derived from the metric units in order to measure smaller or larger quantities.
So we can conclude that Standard International system is a system is used to measure physical properties.
